- \class Core::Id
- \inmodule QtCreator
-
- \brief The Id class encapsulates an identifier that is unique
- within a specific running \QC process.
-
- \c{Core::Id} is used as facility to identify objects of interest
- in a more typesafe and faster manner than a plain QString or
- QByteArray would provide.
-
- An id is associated with a plain 7-bit-clean ASCII name used
- for display and persistency.
